I need to a build a webapp that allows any number of web-based clients (on smartphones) to increment/decrement a number. Each client's current number should be stored on a server so another app can read the list of current numbers and visualize the results in real time.<p>I haven't done much in the webapp space so am looking for tech suggestions on ways to about this.<p>I figure I could certainly do PHP/MySQL, but I want an ajax feel to the app (no page reloads). I've noticed options like Firebase/Meteor/Derby and am wondering if that might be a good way to go---avoid the DB all together. Are there other options I should be looking at?<p>Thanks for any help.
[meteor dev] Meteor + Mongo may be a good choice for you. The leaderboard example at <a href="http://www.meteor.com/examples/leaderboard" rel="nofollow">http://www.meteor.com/examples/leaderboard</a> already has a lot of what you need. The trick is figuring out how to identify each client: whether you have users log in or just assign a unique ID to each client.
Ajax feel is client-side, and have no implications on how the actual storage is implemented (server-side).<p>With specification only given the above, I'm sceptical on whether you'd need a database in the first place -you can eg. write directly to a file without any hassle.
